BUILDING-WALL CONSTRUCTION.

Application mea april 27, 1920. sena; Nq. Samia.

This invention relates to an improvedy building wall construction, and more particularly to a wall construction made up of.`

stone, brick and the like, and having in" corporated therewith as a fixed part thereof novel means of furring.

It is a matter of common knowledge that Walls, either brick or stone, when built solid are high conductors of heat, with the result that, particularly in cold weather, if there is much moisture in a room bounded by solid walls, the moisture will condense and freeze on the walls. Moisture also by capillary attraction will go through solid masonry walls. This is also true to a considerable extent when the walls are formed' of hollow tile wherev the mortar joints go 'through the wall. To overcome this Iand other difficulties, it is the custom to` supply a furring on ythe inner suraoe of the wall, This furring, in the most usual practice, takes the form of strips of wood attached to the wall, and to these strips the lathingv is applied, leaving a space the thickness of the furring between the wall andthe lathing and plaster. It has also been suggested to provide tile as a furring, the tilebeing placed against the interior surface of the wall, but in all prior constructions along this line with which I am familiar, the tiling is more or less insecurcly mounted into position and the joints between adjacent vtiles form lines of conductivity.

It is the primary object of the present invention to overcome existing objections and defects in the previous methods of furring, and to this end it is proposed to provide a furring having all of the advantages of revious furrings, with means for more Emily anchoring the furring in place, so that the furring, in edect, constitutes a continuation or integral part of the. wall and in .a manner to eliminate mortarjoints between die van, 'and placer, ,the furrmg .also belngof a eharacter'whereby the plaster may be readily and firmly applied'directly thereto and complete the. insulation.

In the preferred embodiments of the invention, herein illustrated and described, I provide a. furring constructed ofhollow tile blocks or sections, the blocks being of a construction whereby parts thereof reject into, and are bounded by the brie?, stone, or other make-upof the body portion of the wall, with the result that when the wall is completed, vthe furring constitutes a'iXed or incorporated portion thereof, and the `furring being of a construction whereby to provide substantially continuous air spaces or voids over the wall.

The invention also includes a novel and improved construction of furring tile,

More particularly, the invention includes a novel and improved wall construction simple in design and construction, comparatively inexpensive to produce, strong and durable, and combining with the ad vantages of wall constructions at present in .us e, m any additional advantages,`with the result that an insulated wall of very 10W Condutvty is provided, and the expense 0f lathng and applied furrpg .eliminated.

Other improvements, and. novel details. in they construction and arrangement' 'of the parts 0f my improved Well and terrine, will be appreciatedrfrom the description to folf low, which, fora clear understanding of the invention is to be considered, in connection with the accompanying drawings, which form a part hereof and wherein is disclosed for purposes of illustration, convenient and satisfactory embodiments of the invention, although it is to be borne in mind in this connection that minor changes in details may be resorted' to'without def parting from the spirit of the invention.

In the drawings, Fig. l is a vertical section of a'wall,k broken away, constructed in accordance with my invention;

Fig. 2 is an enlarged detail view of one of the furring tiles which constitute a part of the wall; and

Fig. 3 isa vertical section of a slightly modified form of wall and associated furring.

lVith more particular reference to Figures 1 and 2 of the drawings, wherein like reference numerals refer to corresponding parts throughout the several views,l represents generally the outer face of the wall, being made up of a series of bricks, stones, building blocks or the like (1) having the usual mortar joints 2. Arranged in overlapped relation with respect to the bricks l are furring tile, conveniently of substantially T-shaped formation in section. In this embodiment of the invention, the stems or load receiving body portions 3 of the tile blocks project between the bricks l, with the outer 'faces thereof 2a in substantial alinement with the outer faces of the bricks l, so that portions of the furring constitute in effect a continuation of the outer face of the wall the body part of which is formed by the bricks 1. The horizontal stem portions of the furring tiles are sub'- stantially coextensive with the thickness of the facing bricks l, and the said stem connects by curved portions or heavy fillets 3a, with an upstanding flange portion 4 and a depending flange portion 5, which form a relatively thin furring portion. These flange portions extending at right angles to the stem 3 and bricks l, areadapted to overlie the inner surfaces of the bricks 1 so that when laid in a wall with the upstanding flanges on one row of tiles coming in close juxtaposition with the depending flanges on the superimposed row of tiles at a point substantially midway between the top and bottom of the bricks 1, form a substantially continuous interior covering or furring for the bricks. By reason of the peculiar construction of tiles, continuous voids or spaces 6 are provided, extending substantially continuously from one side of the wall to the other. The furring tiles are of course hollow, the stem being provided with openings 7 therethrough, and the hanged head with openings, 8 therethrough. The inner faces of the tiles are provided with a series of grooves or recesses for the reception of mortar, thereby forming mortar joints 9 whereby to provide suitable anchoring means for the plaster 10 which is applied directly to the tiles.

From the construction above described it will be appreciated that the mortar joints 2 do not extend to interconnect with the plaster, but the flange portions of the tiles overlie these joints which connect with the voids G previously described.

As thus constructed, the tile furring constitutes an integral portion of the wall construction, the bricks and tiles at the face of the wall being arranged in alternate relation throughout the surface of the wall.

ith a view to fascilitating assemblage and reducing labor in constructing the wall and furring, the furring arrangement may be slightly modified as illustrated in Fig. 3, wherein the vertical thickness of the stem or tongue would be substantially that of two or more of the. facing bricks, and in this embodiment of the invention the bricks, being given the numeral 10a, with the interposed mortar joints l1 constitute the entire outer face of the wall. But in this construction as in the previous one described, bricks overlie the top and bottom surfaces of the tongues 12 of the tiles, and the crosspart or head of the tiles, by means of the flanges 13 projecting over the upper and lower edges of the over-lying bricks, whereby the mortar will not be in connection with the plaster through the joints, and whereby the voids are maintained as before. The bricks which overlie the tongues or stems of the tiles may be of a length to project from the outer face of the wall to the inner end of the stems as illustrated at 15 or these bricks may terminate substantially with the outer end of the tiles as illustrated at 16, in which latter event an auxiliary face brick 17 is arranged in line with the brick 16 and jointed to the latter by mortar.

ln this modified form of construction, as in the previously described construction, the furring may be provided on its inner surface with scored or curved portions 18, to which inner surface the plaster is directly applied. Likewise, as in the previous construction, it will be observed that the furring constitutes in effect an integral portion of a composite wall comprising bricks or blocks and furring.

It is obvious of course that the blocks used in the formation of the facing wall, may take different forms and materials, and wherein the term brick or bricks is employed for instance, inthe description and claims, this term is not to be construed as a limitation, but rather as a general term i including within its meaning, bricks, stones,

building blocks, material.

l/Vhat I claim is:

1. A furring tile comprising a relatively thick wall forming body portion for receiving the load and a relatively thin furring portion having transversely extending dead air spaces therein, the furring portion extending beyond the top and bottom of the load receiving body portion and connected thereto by inwardly curved portions tov form a dead air space, in a built up construction, in front of those portions of the wall between the load receiving body portions.

2. A furring tile comprising a relatively thick wall forming body portion for receiving the load and a relatively thin furring portion having transversely extending dead air spaces therein and transversely extending mortar receiving grooves in its outer and other like building face, the furring portion extending beyond the top and bottom of the load receiving body portion and connected thereto by in- Wardly curved portions to form a dead air In testimony whereof I have hereunto WILLIAM O. JOHNSTONE.
